Refractory multi-principal element alloys (RMPEs) comprised of Hf, Mo, Nb, Ru, Ta, W and / or Zr are of interest for high temperature applications. Relative to their FCC counterparts, the composition space for RMPEs remains relatively underexplored, due to difficult processing paths and high melting points. This presentation will discuss sequential alloy design of RMPEs guided by machine learning approaches that are coupled with rapid processing and characterization. Building on a recently published refractory alloy database, a machine learning model was trained to identify promising compositions. Experimental methods, including splat quenching as a rapid solidification technique and thin foil tensile testing have been developed to rapidly explore novel RMPE compositions with interesting properties. New compositions with high strength will be discussed.
